MECHANICAL OILER FQR SHAFTING.

SPECIFICATIQN forming part of Letters Patent No. 553,512, dated January28, 1896.

Application filed February 27, 1895. Serial No. 539,845. (No model.)

To all whom t may concern.-

Beit known that I, GEORGE H. COLE, a citizen of the United States,residing at Lowell, in the county of Middlesex and Commonwealth ofMassachusetts, have invented a certain new and useful Improvement inMechanical Oilers for Shafting, of which the following is aspecification.

My invention relates to mechanical Oilers i for shafting; and itconsists in the combinations hereinafter described and claimed, theobject of the same being to feed the oil continuously in largequantities from a reservoir in the journal-box t0 the journal-bearing,to return the surplus oil to said reservoir, and to prevent the oil fromgetting beyond the ends of the j ournal-box, running to waste anddirtying the shafting and the floor beneath and articles resting uponthe floor.

In the accompanying drawings, on two sheets, Figure l is a plan of apiece of shafting provided with a collar and arranged in a journal-box,said box and my improvement; Fig. 2, a vertical central longitudinalsection of said journal-box and the toothed Oilerring, showing saidshafting and the oilershaft pulley and pinion in front elevation; Fig.3, a front elevation of a part of the journal-box, shafting, andoiler-shaft, showing' the oiler-shaft provided with a face-wheel and theshafting provided with a fast gear; Fig. 4, a side elevation of saidface-Wheel and fast gear; Fig. 5, a plan of the journal-box, shaftingand movable deflector, the cover being removed to show the oiler-shaftand its pinion and the oiler-ring.; Fig. 6, a plan of the lowerhalf ofthe journal-box, the shaftin g and collar, the oiler-ring,y the Wipers,a stop-ring and packing-ring, one of said wipers, the posts whichsupport the lower half of the Babbitt metal lining and the oil-passageswhich lead from the opening between the babbittings to the reservoir,being shown in dotted lines; Figs. 7 and 8, vertical transverse sectionson the lines 7 `7 and 8 8, respectively, in Fig. 2; Fig. 9, a frontelevation of the adjustable oil-deflector detached; Fig. 10, a planofthe oil-wipers and adjacent parts of the lower babbit-ting; Figs. 11and 12, respectively, a front elevation and a side elevation of a partof the oiler-ring and the pinions connecting said ring and theoiler-shaft, by which the surface speed of said oiler-ring may be madedifferent from that of the shafting to be oiled,

parts of the cap of the journal-box being shown in central longitudinalsection in Fig. 11, and the shafting being in front elevation in Fig. lland in vertical cross-section in Fig. 12.

The piece of shafting A may be provided with a fixed collar a to preventend movement of said shafting in the usual manner.

The journal-box B consists of a cap B and a lower half B2, in which theshafting A is supported. The lower half B2 is provided with ears b, bywhich the box B is supported in the usual manner in any hanger. Saidlower half B2 is provided also with an oilreservoir b2, which extendsnearly from end to end of the same, and with vertical posts b4,preferably cast or otherwise formed in one piece therewith, upon whichposts rests the lower babbitting C', the upper portions of saidbabbitting being held between the sides of said lower half.

The box B has an annular enlargement b vat the middle thereof to receivethe toothed oiler-ring D, hereinafter described, and to allow thesame torun freely out of Contact with said box and the lining or babbitting Cof the cap B, which lining C has the same thickness at c within saidenlargement b' as where said lining comes in contact with the shaftingA. J ust outside of the babbitting or lining C said lower half is'alsoprovided at each side thereof and at each side of the enlargement b'with a horizontal groove bs, which extends from said enlargement to theends of said lining, said grooves bs receiving the lower edges of thecap B and discharging any oil which may work into said grooves bs intocylindrical drip-receiving chambers b3 cast in and continuous in bothhalves of the box B, Figs. 2 and 6. 'The outer edges of the lower liningC are beveled at c2 to form with the inner face of the lower half of thebox grooves which descend slightly fromv the middle toward the ends ofsaid box, as indicated by the dotted line c2 in Fig. 2, so that any oilwhich is caught between said lining C and the lining C of the cap B runsalong in the spaces between said beveled edges o2 and the horizontal.edges es of the lining C and is discharged into the reservoir b2 throughgrooves bm, formed in the IOO inner faces of the lower half and reachingfrom the top of said lower lining C to the top of said reservoir.

The ends of the lower lining C are provided with projections c' orWipers, Figs. 2. and (i,

' which remove the oil from the shafting A and allow the same to fallinto the reservoir in order to prevent, as far as possible, the oil fromcrawling along on said shafting and out of the ends of the j ournal-box.If the shafting is intended to run always in the same direction thefront side c of the wi per c, or side toward which the oil is carried,should be inclined to the axis of said shafting in such a manner as todirect the oil toward the body of the lining C', and the rear side c5 ofsaid wiper should also be inclined in the same direction, as shown atthe right in Fig. G; but if the shafting is intended to run in eachdirection, at will, both sides cG of said wiper should be parallel withsaid axis. I also provide near each end of the box B, in the top of thecap B and just beyond the ends of the lining' C, a nearly tria-ngularhole D7, Fig. 5, in Which is placed a deiector E, preferably of metal,and hinged to said cap B' bya staple-shaped hook e, one arm of whichenters a vertical hole e in said dei'lector near the outer edge of saiddeflector, and the other arm of which hook c enters a hole b5 in the capB, Figs. 2 and 5, in such a manner as to allow said delector to be swungby the friction of the shafting A `on the bottom thereof to cause oilcarried by said shafting beyond the ends of the lining' to be turnedtoward said lining.

As a further precaution against the oil reaching the ends of thejournal-box, I surround the shaftin g A, between the defiectors E andthe ends of said box, with stop-rings F, of any material, which iit saidshafting closely and prevent the oil from passing between said shaftingand said rings F, and which may be readily secured in place, preferablyusing leather strips, the ends of which are fastened by wire belt-hooksf of ordinary construction.

Such oil as, notwithstanding the Wipers e.

and deilectors E, reaches the stop-rings F will be thrown by centrifugalforce from the eircumferences of said stop-rings into the box B and iiowback to the reservoir.

Dust and lint are excluded from the box B by means of packing rings orstrips G inserted in grooves Z915 bm, substantially in the manner shownin my Patent No. 515,745), dated March 6, ISM.

The oiler-ring I) surrounds the shafting A and rests thereon, asdescribed in said previous patent, but instead of being a mere ringcarried by the direct friction of said shafting thereon is an annulargear, driven by an oiler-shaft II, provided with a pinion h', which maydirectly engage the teeth d of said ring D, as shown in Figs. 2, 5 and7, said oiler-shaft H being rotated by a Wheel which may be afriction-Wheel 7L, fast on said shaft H and driven by contact with theshafting A, as shown in Figs. l, 2 and 5, or a gear 7L,

fast on said shaft II and engaging another gear 7a4, fast on theshafting A, as shown in Figs. and i, where the gear h5 is represented asa face-gear or contrate-gear and the gear 7L* is represented as a ringhaving teeth on the edge thereof.

The arrangement shown in Figs. 3 and i gives to the oiler-ringapositivemotion in the same direction of revolution as that of the shaft, causingthe contiguous surfaces of said oiler ring and shaft to travel in thesame direction.

By using any other odd number of engaging pinions in place of the pinionh to conneet the oiler-shaft and the oiler-ring, said ring will still becaused to rotate in the same direction as said shafting A, and by makingone of these pinions a compound pinion or a compound gear, as shown ath3, Figs. Il and l2, the speed of said ring may be reduced below that ofsaid shafting, which lessens the liability of the oil to be so violentlyagitated as to be driven beyond the journal-surface of the shafting tobecome iilled with air-bubbles, which diminish the lubricating qualityof the oil.

A guide-cap I, Figs. 2, 5, 7, and S, is provided with notches t' Q1 toallow said guidecap to be placed down in the chamber b oi' the cap B andover the pinion 7L', or over the Series or train of pinions shown inFigs. Il and l2, and prevents any endwise movement of the oiler-sh aft,which lies looselyin a groove Z211, reaching down from said chamber b9to the end of the box B, said chamber Zi and groove b being closed by asuitable cover J, having a suitable shape to iill said chamber andhaving a iiangej to rest upon the top of the cap I3.

The oiler-ring I), for convenience of application to the shafting, maybe made in two parts d d2, halved together at d3 and secured to eachother by pins (Zt (Shown in Figs. G and 7.)

I claim as my invention*- l. The combination of a j ournal-box havin g'a suitable reservoir, atoothed ring or annular gear adapted to surroundand rest upon a piece of shafting supported in said journalbox, and toenter the oil in said reservoir, an oiler-shaft having a fast pinionadapted by its rotation to rotate said oiler-ring and having a wheelfast thereon and adapted to engage said piece of shafting and to berotated thereby, as and for the purpose specified.

2. The combination of a journal-box having a lower half provided with asuitable reservoir and having a cap provided with a chamber, a toothedring or annular gear adapted to surround and rest upon a piece ofshafting supported in said journal-box, and to enter the oil in saidreservoir and an oiler-shaft having a fast pinion adapted by itsrotation to rotate said oiler-rin g and to enter said chamber and havinga Wheel fast thereon and adapted to engage said piece of shafting and tobe rotated thereby, and a guide-cap, hav- IOO IIO

ing notches and adapted to be placed in said chamber over said pinionand oiler shaft, as

' and for the purpose specified.

tional contact of said shafting, to direct oil escaping from said liningalong said shafting back toward said lining, as and for the purposespecified.

In Witness whereof I have signed this speciiication, in the presence oftWo attesting Witnesses, this 21st day of February, A. D.1895.
